摘　　要：针对在干旱草原区生态脆弱期 (冬春季节 )放牧家畜 ,导致植被严重破坏和家畜跑青掉膘的“双损”现象 ,在该期进行了绵羊禁牧舍饲饲养和反季节育肥试验。并与该时期放牧绵羊在体重变化、经济效益、生态效益等方面进行对比分析。结果表明 ,在草原生态脆弱期采取绵羊较低成本禁牧舍饲是维护草原生态安全的较好方式 ,同时结合该期羊肉价格较贵的特点 ,搞好冬春反季节育肥出栏 ,则是促进生态效益和经济效益协调统一 。Animal grazing during the ecological frangibility period(from April to June)results in both the weight loss of livestock and the deterioration of rangeland in Northern China. To avoid the occurence of this situation, different sheep raising methods in rangeland were conducted. The liveweight change of sheeps, ecological and economic benefits were analyzed. The results showed: non-grazing? yard feeding and fallen sheep in reverse season were ideal way to protect the eco-system and to increase the benefit of...
